Question 1

How do I install Vala Language Server on Ubuntu?

Accepted Answer

Install from the OBS repo using the provided link or via package managers, as detailed in the installation section for Ubuntu and other Debian-based systems.

Question 2

Vala Language Server or GNOME Builder's built-in Vala support?

Accepted Answer

VLS offers standardized LSP features across multiple editors, while GNOME Builder has native integration but is IDE-specific. For editor flexibility and consistent features, VLS is better, but Builder might suffice for GNOME-centric workflows.

Question 3

How to set up VLS for a Vala script without a build system?

Accepted Answer

Add a shebang line like '#!/usr/bin/env -S vala --pkg gtk4' to your Vala file, and VLS will use that to understand dependencies, as explained in the specifying dependencies section of the README.

Question 4

Does Vala Language Server work with Genie language?

Accepted Answer

Yes, VLS supports both Vala and Genie languages, providing code intelligence features such as autocompletion and diagnostics for Genie, as stated in the project description and filetype configurations.

Question 5

What's the best editor to use with Vala Language Server?

Accepted Answer

VS Code with the official Vala plugin is highly recommended for ease of setup, but Vim with coc.nvim or GNOME Builder also offer robust integration, based on the detailed editor support in the README.

Question 6

Why is VLS not finding symbols in my project?

Accepted Answer

Check if you have a build script like meson.build, compile_commands.json, or a shebang in your file, as VLS requires these to analyze dependencies, per the important note in the README about build system detection.
